Versuchsvorschrift
5′-tert-Butoxycarbonylamino-2′-trifluoromethoxy-biphenyl-4-carboxylic acid ethyl ester (200 mg) in ethanol (7 ml) and 2M sodium hydroxide (4 ml) was stirred at 20 C for 18 h. The ethanol was then evaporated and the residue acidified. The solid thus formed was collected by filtration and dried (128 mg)
